Abstract
The invention discloses a preparation method of antibacterial and anti-ultraviolet fiber/fabric loaded with nano-titania. The preparation method comprises the following steps: dissolving butyl titanate in an organic solvent, adding the fiber/fabric in the solvent and carrying out adsorption processing; and placing the fiber or fabric after the adsorption processing in air for drying, or processing the fiber/fabric in water, thus obtaining a product. According to the invention, butyl titanate is adopted as a nano-titania precursor, the nano-titania is generated through adsorption, in situ hydrolysis and polymerization of the butyl titanate on the surface of cotton fabric and nanopores in the cotton fabric, so that the preparation method is simple in operation, high in raw material availability, does not need any acidic raw materials, and can avoid the damage to the strength of the fiber and fabric. The product prepared by the method disclosed by the invention has soft handfeel, durable antibacterial and anti-ultraviolet performances and can be washed for multiple times.
Description
Technical field
The present invention relates to a kind of antibiotic, antiultraviolet fiber, process for making such fabric of load nano-titanium dioxide.
Background technology
Antibiotic, the anti UV finishing of fabric use maximum nano titanium oxides that is at present.Utilize nano titanium oxide that the method that fabric or fiber carry out modification is mainly comprised direct method and post treatment method.Direct method refers to the direct wire drawing of the fiber mixing of nano titanium oxide and fusion, and this method is applicable to synthetic fiber.Post treatment method refers to be put nano titanium oxide in order on fabric through the means of padding or binding, and its scope of application is more extensive.Post treatment method is divided into two kinds of situations: first kind, use nano-titanium dioxide powder and dispersant binder etc. to be made into functional finishing agent, fabric is put in order, its shortcoming be feel bad, be not suitable for and wear next to the skin, and easy wash-out; Second kind, use butyl titanate, acetic acid, ethanol etc. to be feedstock production colloidal sol, be padded on the fabric, drying and dewatering then, original position generates titanium dioxide nanoparticle, and its shortcoming is that colloidal sol is acid, the intensity of damage cellulose fiber peacekeeping fabric.
Summary of the invention
The object of the present invention is to provide a kind of easy and simple to handlely, the prepared using degree is high, utilizes antibiotic, antiultraviolet fiber, the process for making such fabric of the load nano-titanium dioxide of in-situ hydrolysis polymerization.
Technical solution of the present invention is:
(1) butyl titanate is dissolved in the organic solvent, adds fiber or fabric, adsorption treatment;
(2) fiber or the fabric after will adsorbing places air drying, or places water to handle, the uvioresistant product.
(3) reacted fiber or fabric placed contain inorganic antibacterial ion solution adsorption treatment, antibiotic, uvioresistant product.
Step (3) directly places reacted fiber in the air or in the aqueous solution and contains inorganic antibacterial ion solution adsorption treatment; Or step (2) and (3) merge, and the fiber after the absorption or fabric are placed contain the inorganic antibacterial ion solution, and polymerisation and adsorption treatment are carried out synchronously.
Said organic solvent is absolute ethyl alcohol, acetone or isopropyl alcohol.
In butyl titanate and the organic solvent total amount, the percent by volume of butyl titanate is 1 ~ 20% in the step (1).
The bath raio of butyl titanate solution and fabric or fiber is 1 ~ 50 in the step (1).
The time of adsorption treatment is 5 minutes-2 hours in the step (1), treatment temperature: room temperature ~ 70 ℃.
Drying is to dry or 40-120 ℃ of oven dry in room temperature in step (2) air; Said when placing water to handle, temperature is: room temperature ~ 90 ℃, time 0.5-4.0 hour.
It is the nano titanium oxide precursor that the present invention adopts butyl titanate, generates nano titanium oxide through butyl titanate in absorption, in-situ hydrolysis, the polymerization of cotton fiber surface and inner nano pore, and COTTON FABRIC is carried out the uvioresistant modification.Utilize above-mentioned approach that natural fabric is carried out modification, not only easy and simple to handle, the prepared using degree is high, and need not use any acid material, can avoid the damage to fabric and fibre strength.Product is soft; After experiencing 50 washings, still have antibiotic uvioresistant performance (washing procedure: standard soap flakes liquid detergent concentration 2g/L, bath raio 1:30; 40 degree washings 5 minutes) method is applicable to cellulose fibre and fabric thereof; Like cotton, fiber crops, viscose glue and real silk fabric etc., can be used for health-care underclothes, medical gauze, clothes, drapery etc.
Below in conjunction with embodiment the present invention is described further.
The specific embodiment
A kind of antibiotic, antiultraviolet fiber of load nano-titanium dioxide, process for making such fabric comprise the following steps:
(1) butyl titanate is dissolved in the organic solvent, adds fiber or fabric, adsorption treatment;
(2) fiber or the fabric after will adsorbing places air drying, or places water to handle, the uvioresistant product.
(3) reacted fiber in the air or in the aqueous solution directly placed contain inorganic antibacterial ion solution adsorption treatment, antibiotic, uvioresistant product.
Said organic solvent is absolute ethyl alcohol, acetone or isopropyl alcohol etc.
In butyl titanate and the organic solvent total amount, the percent by volume of butyl titanate is 1 ~ 20% (example 1%, 10%, 20%) in the step (1).
The bath raio of butyl titanate solution and fabric or fiber is 1 ~ 50 (example 1,25,50) in the step (1).
